Right now, that honor goes to Grand Theft Auto IV's Auf Wiedersehen Petrovic. Once Seriously 3.0 from GoW 3 is done, however, a new king will be crowned.---The official Howard the Duck of the MvC3 board!

Forza 4, I'm still in the middle of the 2 achievements that require buying the 5 most expensive cars in the game, and all the Ferrari's on disc 1.

Trying to buy those cars on the auction house is pointless, there's a s***load of trolls who endlessly bump up the price of the needed cars to 1% under retail, it's not worth the waste of time.---"Those who would give up essential liberty to purchase a little temporary safety deserve neither liberty nor safety."Ben Franklin

Anything that requires finishing the game without getting hit (or 1CC's), and I've done plenty of them, some I will probably never attempt due to their sheer difficulty, but who knows...>_>---"The Alternate Truth is yet to be Found" - XBL/PSN/YT/TW: NeoStrayCat (=^_^=)

Once and done is all I can say. I'll never put myself through that kind of hell again.

That or the character trophy achievements for Star Ocean 4. I don't know which one was more of a pain in the ass, really.---Your = belonging to you, you're = you are, their = belonging to them, they're = they are, there = not here.
